Notes

// **Set dimensions for A4 size**
const pdfWidth = 595.28; // A4 width in points
const pdfHeight = 841.89; // A4 height in points

// **Create a new PDF document and add an A4 page**
const pdfDoc = await PDFDocument.create();
const page = pdfDoc.addPage([pdfWidth, pdfHeight]); // A4 page size

// **Register fontkit and embed the custom font**
pdfDoc.registerFontkit(fontkit);
const customFont = await pdfDoc.embedFont(brandonTextBase64Regular);

// **Embed the image into the PDF**
const pngImage = await pdfDoc.embedPng(imgData);

// Scale the image to fit within A4 page without distortion (optional: scale to fit inside the page)
const scaleX = pdfWidth / pngImage.width;
const scaleY = pdfHeight / pngImage.height;
const scale = Math.min(scaleX, scaleY); // Maintain aspect ratio

page.drawImage(pngImage, {
x: (pdfWidth - pngImage.width * scale) / 2, // Center the image horizontally
y: (pdfHeight - pngImage.height * scale) / 2, // Center the image vertically
width: pngImage.width * scale, // Scaled width
height: pngImage.height * scale, // Scaled height
});

// **Set width for input fields**
const inputFieldWidth = pdfWidth * 0.6; // 60% of the A4 page width

// **Define positions for the input fields with specified layout**
let positions = [
{ x: 50, y: pdfHeight - 245, width: inputFieldWidth, height: 110 }, // First input box (near top)
{ x: 50, y: pdfHeight - 674, width: inputFieldWidth, height: 42 }, // Second input box (above third)
{ x: 50, y: 33, width: inputFieldWidth, height: 100 }, // Third input box (near bottom)
];

// **Create and add input fields with updated font size**
const form = pdfDoc.getForm();
positions.forEach((pos, index) => {
const textField = form.createTextField(`field_${index}`);
textField.enableMultiline(); // Enable multiline for text field

textField.addToPage(page, {
x: pos.x,
y: pos.y,
width: pos.width,
height: pos.height,
textColor: rgb(0, 0, 0),
font: customFont,
borderWidth: 1,
backgroundColor: rgb(1, 1, 1),
});

// Adjust font size dynamically based on field height
const fontSize = Math.min(10, pos.height / 12); // Font size adjusted based on field height (avoid overflow)
textField.setFontSize(fontSize);
textField.setMaxLength(200);
});

// **Save the PDF document**
const pdfBytes = await pdfDoc.save();
